node.js handelbars Error: Missing helper: "compare"

when I run this code to comparing value if it bigger than one i get this error 

{{#compare pageCount ">" 1 }}
  <ul class="pagination"><­/ul>
    {{#compare currentPage ">" 1 }}

       <li><a href="/?page=1"> &laquo;</a></li>
    {{/compare}}

{{/compare}}

i installed handelbars with node.js and i tested it but i get this error always when i use compare hash ?

You must make a custom helper with Handlebars.registerHelper you can check the full documentation to know how to register a custom helper to be able to use it in the template.
